Evaluation of a Pneumotachograph (SPI) for the Production of PET and CT Acquisitions Synchronized With Breath for the Assessment of Extension of Lung Cancer

This is a pilot study, single-center, prospective, open-label, to assess the acceptability and performance of the experimental medical device (SPI) used during an imaging examination (PET / CT 4D imaging in synchronized mode centered on the thorax). Each patient will be its own control, since the imaging examination will be synchronized simultaneously with the two systems: tested Medical Device (SPI) and reference Medical Device(RPM).

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patient for whom there is an indication of PET/CT 18FDG imaging for thoracic oncology ; this indication is consistent with the Standard Options Recommendations or was validated during Multidisciplinary Consultation Meeting :
  • Either an extension assessment of non-small cell lung cancer;
  • Either the characterization of single pulmonary nodule; Or - the definition of the target volume in radiotherapy.
  • Patient who meets the following criteria to be eligible for an PET/CT imaging:
  • Patient able to maintain a supine position for 60 minutes
  • Patient with no bronchopulmonary infection and with no upper aero digestive tract acute infection in progress (increased risk of false positives)
  • Age ≥ 18 years
  • WHO ≤ 1
  • Well-informed written consent signed by the patient and collected before any specific procedure in the study
  • Patient member in a national insurance scheme

Exclusion criteria

  • Patient with a bronchial carcinoid or bronchoalveolar cancer
  • Patient with acute bronchopneumopathy
  • Not stabilized diabetic patient
  • Patient with an absolute indication against spirometry: ongoing pneumothorax or within the previous month, pleural biopsy or puncture within the previous month, hemoptysis, severe asthma, tuberculosis
  • Any usual relative indication against spirometry: ongoing bronchial infections, acute asthma, decompensation of chronic respiratory failure, respiratory pain
  • Any usual formal indication against imaging examination PET/CT (important claustrophobia)
  • Patient unable to follow study procedures
  • Pregnant women or nursing mothers can not participate in the study
  • Men and women of childbearing age must use effective contraception at study entry and throughout the study
  • Any other medical conditions making the inclusion of the patient in the study inappropriate in the opinion of the investigator
  • Patient under legal guardianship

Treatment and study plan

PET/CT 4D imaging in a synchronized mode centered on the thorax.

Device

Primary outcomes

  1. Feasibility of the PET/CT synchronized exam with SPI device ("success" or "failure" )

    Time frame: 2 years

    feasibility is evaluated in a composite end point (success will be obtained in case of concomitant success of the 4 sub-criteria assessment):

    • Tolerance / acceptability of the patient to breathe into SPI throughout the examination)
    • Detection of breath cycle of the patient by measuring dCycleSpi (dCycleSpi = Number of synchronization signals emitted by SPI / total number of breath cycle * 100).
    • Accuracy of detection of inspiratory peak amplitudes with SPI medical device: by measuring dtSpi (dtSpi = standard deviation of the time lag between synchronization signals and maximum inspiratory amplitude for each cycle).
    • Production of images with a correct segmentation of BTV during PET/CT synchronized exam with SPI device"

Secondary outcomes

  1. Measure of dCycleRpm (dCycleRpmi = Number of synchronization signals emitted by RPM / total number of breath cycle * 100)

    Time frame: 2 years

  2. Accuracy of detection of maximum inspiratory amplitudes with RPM medical device: evaluated by measuring dtRpm

    Time frame: 2 years

    dtRpm = standard deviation of the time lag between synchronization signals and maximum inspiratory amplitude for each cycle

  3. Measure of BTVrpm (= biologic tumoral volume)

    Time frame: 2 years
